What is Hypertension
Hypertension occurs when the pressure in the arteries becomes high, causing the heart to work harder than normal to pump the blood throughout the body.

Blood Pressure Defined
The pressure in the arteries when the heart beats and when it is at rest.
Systolic: pressure during a heart beat (the top number)
Diastolic: pressure when heart is at rest (the bottom number)

The Heart As A Pump Certain nerve impulses cause
arteries to constrict and dilate. The heart pumps blood through
the vessels. If the vessels are wide open, blood
flows freely. If vessels are narrowed, more pressure is required for blood to flow through.

How to Control Blood PressureSTOP SMOKING
The nicotine present in tobacco products causes:
Decreased oxygen to the heart.
Increased blood pressure and heart rate.
Increase in blood clotting. Damage to cells that line
coronary arteries and other blood vessels.

When All Else Fails Sometimes even
doing all the right things will not lower your blood pressure to an acceptable level.
When that happens, your doctor may put you on one or more blood pressure medications.
